The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
If the length of a side of the square is S units then the diagonal is S*sqrt(2) units in length.
~26.16 units.
The length of the diagonal of a square whose side lengths are 7 square root 2 (9.89949494) is: 14 units.
Using Pythagoras' theorem each side will be 6.363961031 units in length.
The diagonal is 33.941 units.
If the length of a side of the square is S units then the diagonal is S*sqrt(2) units in length.
11.3137085 units
About 11.31 units.
Given the length of the diagonal of the square ... call it 'D units'. The area of the square is (1/2 D2) (same units)2.
Using Pythagoras' theorem which says that the square on the hypotenuse (in this case the diagonal) is equal to the sum of the squares on the other two sides (which in the case of a square would be equal in length). so if the diagonal measured 10 units, the square on the diagonal would be 100 square units. And as this = 2*the squares on the other sides, the square on one side would be 100/2 = 50 square units. As a square has sides of equal length the square on one side is actually the area of the square. i.e. the area of a square with a diagonal of 10 units is 50 square units. or generically the area of a square with a diagonal of length 'x' = (x2)/2
Use Pythagoras' therom: 32+32 = 18 The square root of 18 is 4.242640687 units which is the length of the diagonal.
sqrt(12.5) units
~26.16 units.
The length of the diagonal of a square whose side lengths are 7 square root 2 (9.89949494) is: 14 units.
d=x√2 where d is a diagonal and x is a side d=80√2 (or 113.137)
If, by diagnole, you meant diagonal, and that its length was 12√2 units, then the area is 144 square unit.
Using Pythagoras' theorem each side will be 6.363961031 units in length.
